Referring now tothe drawings: Reference "5 character i4 (Fig. 2) designates la base'of an ordinary punch press ywith which is integrally united a standard 5l). Adjustably -fsecured for vertical movementvto the standard 50 -vis a`-tab1e 35. the same being bolted lto the Istandard kby l0 vmeans of bolts 4h41', 42, vwhichpass through longitudinal slots .89, 8-9, -in said table (Fig. 51)'. To facilitate theraisingor lowering of vthe-"table, there is provided an elevating screwB-'I with which is engaged-a threaded hand'whee138. The upper 1'5 portion of elevating screw 31 is reduced and seats within av suitable recess provided -in a lug *36 formed'integrally with the table 35 and dependingdownwardlyvfrom said'table. I

'Slidably mounted -Aupon vthe Ltablel 135 is apair 20 Vof bearing y brackets 20, 20' ywhich are vsupper-ted in guideways 52A, T52-A' .(Fig. 2), said brackets being provided with guides 52 fitting within `said guideways. The table -brackets may be adjustably moved towards and from each Vvother lrby 25 means of anvadjustingscrew 33 heldin position by 'a' bearingv 32 formedontable 35 andfsaid screw l33vengages-with nuts-53, V53', formed integrally with the brackets 20, V211i', respectively.

Mounted upontheexlter-ior of -said shafts192,`92" arefa .pair of hol- 40 low shafts 86, 86 having exterior `.screw threads 23,123. Each shaftl86, lhas'threadedionflt an annular nut LIB, I9', respectively, each. nutifbeingV provided with a plurality of'laterallyextending truss hoop ldriving arms '|-1,.said armslbeing 45 securedto their respective nutsfbyiboltssli. :Re tainingirings A21,"j2l are securedto shafts 92,6192' by means'v of screws 22,'22' andserveto prevent longitudinal movement `of .the shaftsxs, 86".

Rotation of the face plates l19, 19 -is :eiected 50 through gears-8,118 which-meshl-with'piniongears 54,54keyed on shaft 55, journalledainbearings 51,51. -A hand leverA 58 is secured upo-nfthe oishaft 55-for rotatingthe pinion. gears54yi5`4", n gears 8,"8 and Yface plates 9,19*. Pinion-gears'S, 55

54' are of suicient length, as shown best in Fig. 7 of the drawings, that when the bearing brackets 2U, 20' are moved away from or toward each other, the meshing engagement of the gears 8, 8' with said pinions will be maintained. Mounted in annular grooves 93, 93 formed in the bevelled side of the respective face plates 9, 9' are a pair of truss hoops I2, I2', said hoops being retained within said grooves by pins I3, I3', pressed outwardly into engagement with the truss hoops by springs I4, `I4' which abut at their inner end against stop pins I5, I5'.

Suitably secured by bolts 3, 3 to the ram I of the punch press is a cross arm 2 to the end of which is pivotally supported by means of bolts 4, 4 a pair of stave bending pressure arms 5, 5'. When a stave is placed in position and they press is actuated to cause the ram to descend, the arms 5, 5 will engage the stave at its ends, forcing the stave ends downwardly onto the tapered front faces of the face plates 9, 9'. The forcing of the ends of the stave downwardly onto the tapered faces of the face plates causes pressure to be eX- erted inwardly on the stave ends in a direction 4 substantially longitudinally of its stave and causes the stave to bow upwardly at the center -into the desired curvature for producing a bilged barrel. After a stave has been bent another stave is inserted, the ram again descends and the operation is repeated until enough staves are inserted between the face plates to form a complete barrel, the bent staves being held in position during the bending of a subsequentstave by engagement under the edges 19, 19 of the truss hoops I2, I2. `After allrof the staves have been bent into position, the punchpress is operated to drive the staves into tight relationship, this being accom- .plished by the action of hammer 5 and anvil 24 which are provided with opposed curved surfaces to correspond to the bilged contour of the barrel, it being .understood that during the hammering operation the stave bending pressure arms are removed. v

After all of the staves have been driven into place, truss hoops I2, I2' are then forced over the ends of the assembled barrel drum to force the staves intoltight sideways engagement. To accomplish this the threaded ring nuts I9, I9 are moved `longitudinally upon their shafts 86, 86' to cause the truss hoop arms I1 to pass through suitable slots formed in the face plates 9, 9 and into contact with the rear faces of the truss hoops I2. Thenuts I9, I9' are actuated by connecting the face plates 9, 9 to one of the truss hoop arms I1 by means of a latch 8I see Fig. 6 pivoted on a bolt II'screwed into the face plates. A spring 62 tends to hold the latch 8| normally against stop pin II), and out of engagement with arm I1. A hand grip I I secured to the latch 8l serves to permitit toV be moved manually to bring its hooked end 82 into engagement with an arm I1 thus locking the armand ring nuts I9, I9 to the face plates 9, 9'.v Rotation of the turning crank 58 will then cause the rings I9, I9' to be rotated through the shaft 55, pinions 54, 54' and gears 8,8'. Due togtherotation of the ring nuts relatively to the screws 23, V23', they will be moved longitudinally of saidl screws tocause the truss hoop arms I1 to force the truss hoops over the assembled and bent staves as shown in Fig. 8. v 4

If it is found that the truss hoops do not draw the staves sufficiently close together, a hammering action by the hammer 6 heretofore described, may be resorted to in which case theV anvil 24 shaped to correspond-to the shape of the inside of the barrel drum, and trunnioned, as at 26, in bearings 25, 25', is brought into operative position by rotation of said bearings 25, 25 on studs 38, 38' projecting from the ends of the shafts 9|, 9 I In order to hold the anvil 24 in operative position, a lock Wedge 28 (Fig. 9) is provided attached to a. draw bar which passes through an opening in shaft 9| and terminates in hand grip 84. Lock wedge 28 is held in locked position by means of a pin 14, which is adapted to engage a notch |80 in said draw bar and which is kept normally pressed against the draw bar by a spring 15, said pin having a handle 16 for releasing it. An additional locking means is provided in the form of a locking pin 94 adapted to engage a recess 95 in shaft 9| to prevent rotation of said shaft. When both of the above named locking means are in locked'position, the anvil 24 will be located directly below the barrel hammer 6 and adjacent the upper inside wall of the barrel drum 68. Unless bearing 25 is locked by wedge 28 in recessr85, and shaft 9| is looked by wedge 94 in recess S5,

Ythe anvil will, by its own weight, swing downward y inside of the barrel. Anvil 24 may be easily Vremoved from its bearings 25, 25' to allow barrel drum 68 to be removed Afrom the machine.

For cutting or kerfing out the grooves in the staves for the reception of the barrel heads and also for facing off the ends of the staves, there is provided a pair of crozing attachments consisting of knives 59, 59' suitably secured as by bolts 60 (Fig. 5) to the enlarged heads21 of the shafts 9|. The construction of each shaft 9| is similar and as shown in Fig. 9 each pro-jects outwardly beyond its bracket 20, 20 and has its projecting outer end supported in bearings 45,` 89 carried by a slide 1 I. Between the bearings 45,* 69, a pulley 11 is keyed to the'shaft, and is driven by any suitable means. When shaft 9I is rotated, the knives 59 will rotate and the knives may be fed to the work by means of an elevating screw 13 having a hand wheel 12 which when turned operates slide 1I, the latter being supported on a projection 91 Vof Ythe ad'jacent'bracket 20 or 20'.

For turning or planing the exterior of the drum, a wood cutting plane B1 (Fig. 2) is suitably attached by a bolt and cable 66 to the face of the ram I, the construction Vbeing such that the plane may be swung from end to end of the drum by hand while the drum is rotated.

The manner in which my machine operates is as follows: A

When it has been decided upon the size barrel desired, the table brackets 20, 20, lare moved either in or out, by turning hand wheel'34 and the stave bending pressure yarms 5 are set in operative'po'- siticn. Punch press tableY 35 is then adjusted to the proper height by nut 38 which in turn operates elevating'screw 31. Truss hoops I2, I2 are then inserted into their respective annular grooves 93, 93 vin face plates 8 and heldtherein by means of pins I3, I3' whicht into openings I5, I5 and are held against the hoops by springs I4, I4. Truss hoops I2, 1 2 project slightly from the annular grooves provided therefor for a purpose laterto be described.

Anvil 24 is then locked in the position'shown in idg.' 1, by lmeans fofwedgez's andlpin 19d .tolassist in the' first stave bending loperation;

Before beginning 'the barrel or drum making `'bperaition 11a suii'icient supply of staves are pre- :paredlbyfsubjecting them 'to fa-thorough steaming linlaccordance withfthe usualwell known practice inthis-art. 1 f Y @The operator then 'takes asteamed stave :and :places it horizontallybe'tween the 'faceplates 9;9'A -asv shown :best 1in viigfl of the drawings, and-trips 'the punch pre'ss';v as vthe ramV l descends, thearms "5, 4:5' 'contact the ends of stave 4I- and'force said fends down onto 'the 'opposed'tapered faces of the lf'ace'plates, and-"the truss hoops, the `'faces of which are 'also-taperedto substantially the same Langle as vthe faceplates. AWhen the press reaches fits ulowermost position, the stave will be fully bent with the ends of the stave engaged under the pro- "truding lower edge portions of fthe -truss hoops l2, 172 I`sothat when thefpresslascenlsl the stave Willlbe 1"held securely in itsbe'n-t form. The operator then turns -crank T58 rotating the face platesthrough shaft l5,fp'inio'ns 54,54', gears Ail, 8 to move the bent stave out of Ithe' `path lof movement of the ramwl. Another stave is then put in place and the-punch pressfagainitrippedto-bend such stave. This operation is continued until a complete barrel drum is formed as shown in Fig. 8 of the drawings. When enough staves to form a complete drum are in place, the operator connects the ring nuts I9, I9 to their respective face plates 9, 9' and again rotates the hand crank 58 to cause said nuts to' be moved in the proper direction to bring the truss hoop driving arms into engagement with the truss hoops I2 and force the latter over the assembled bent staves. The hammering of the barrel by hammer 6 and anvil 24 is next carried out if necessary although in most cases this will not be required, then the planing and crozing operations, all as heretofore described, and by the cooperative action of the correlated parts; all of the operations being carried out without removing any of the staves from the machines, the face plates 9, 9 serving to assist in, the bending of the staves, holding and guiding the truss hoops preparatory to the driving thereof and the holding cf the staves in assembled condition during the hammering, crozing, and planing operations.

While I have shown by way of illustration a construction of a machine which has proven highly satisfactory in practice, it Will be understood that the invention is not limited to the specific constructional details of the machine described and illustrated but that many changes, variations and modifications may be resorted to without departing from the principles of the present invention.
